I would absolutely love to see some development on Dwarven Paladins. The Race/Class combo always seemed so appropriate to me–not just in WoW, but across the fantasy genre.
For example, perhaps a focus on a sub-section of the Silver Hand consisting of Dwarves, like an Ironforge Paladin chapter. In my head-canon, I see my Dwarf as viewing the Light as an extension of the Makers’ (i.e. The Titans) will.
As such, he has devoted himself to a specific Titan and views the Light and his titanic “worship” as interchangeable–similar to how Zandalari Prelates would harness their power from Rezan, or Tauren Sunwalkers from the “sun” itself.
Undoubtedly, many Human Paladins would not be 100% on board with such a viewpoint, and it could make for some interesting ideological clashes and RP.
